The flat needlefish (Ablennes hians) the only known member of the genus Ablennes, is a marine fish of the family Belonidae. Flat needlefish are considered gamefish, frequently caught with the help of artificial lights,[1] but are not often eaten because of their green-colored flesh.[2]
Description
Although they have no spine, they do have several soft rays. There are 23-26 rays on the dorsal fin and 24-28 on the anal.[3] They have 86-93 vertebrae.[3] Dorsally, flat needlefish are blueish, white ventrally, with dark blotches and 12-14 vertical bars in the middle of the body.[4] Flat needlefish have an elongated body, with scythe-shaped pectoral, and anal fins.[3] They also have a dark lobe on the posterior part of their dorsal fins.[3] The longest recorded flat needlefish measured 140 cm long,[5] Measurements for flat needlifish body length do not include caudal fin and head because the fish's long jaws are often broken off.[3] The largest recorded weight for a flat needlefish was 4.8kg.[5]
Distribution and habitat
Flat needlefish are found worldwide in tropical and temperate seas.[3] In the Eastern Atlantic, they are known from Cape Verde and Dakar to Moçamedes in Angola.[6] In the western Atlantic they are known from Chesapeake Bay south to Brazil.[7] They are found throughout the Indian Ocean,[3] and in the western Pacific from the southern islands of Japan to Australia[8] and Tuvalu.[9]
Flat needlefish usually live in neritic ocean waters near islands,[10] estuaries,[11] and near coastal rivers[12] where they feed on smaller fish[1] and occasionally gather in large schools.[2]
Reproduction
Flat needlefish lay eggs, which attach themselves to floating debris via filaments on the surface of each egg[13] Only the left gonad in both sexes is developed, and in males, the right gonad is sometimes wholly absent.[14]
